**■STORAGE**

- Batteries should be stored in a dry, clean warehouse with good ventilation. Avoid direct sunlight and proximity to heat sources, such as radiators (distance should be greater than 1m). Avoid contact with any toxic gases and organic solvents.

- For storage, if the ambient temperature is less than 25℃, the longest storage life is 6 months. For higher ambient temperatures, refer to the specified storage time in the table below:

| Storage Temperature (℃) | ≤25   | 26～33 | 34～40 |

|--------------------------|-------|--------|--------|

| Storage Time (Month)     | 6     | 3      | 1      |

- Batteries should be recharged within their storage life or before use. Charging methods include a maximum charging current of 9.9A, constant voltage of 2.45±0.05V/cell (25℃), and charging time of 15~20 hours. The temperature compensation coefficient is -5mV/℃/cell.
